Sonic 1: Painto Edition 2 (or simply Sonic: Painto Edition 2) is a modification of Sonic the Hedgehog (16-bit), and the first part of the Paintifisation project, made by Painto maniak. The hack contains many features, and is named 'Panto Edition 2' to separate itself from Painto maniak's previous hack; Sonic: Painto Edition (later renamed Sonic: Christmas Island).

A centralised hub world known as The Main Zone. From it, any of the seven zones can be accessed through Giant Rings. There is also a Skill Shop present, from which the player can acquire skills using the rings they've collected
